Patented Jug e 10, 1930 PATENT OFFICE ABRAHAM W. LAIR, 01' LOS ANGELES,CALIFORNIA MASSAGE MACHINE Application filed January 28, 1927. SerialNo. 164,288.

My invention relates to massage machines, and the objects are first, toproduce a mechanism whereby all the varied physiological effects formassage are obtained by alternate "condensation and rarefaction of airwithin a cup placed adjacent the human body, the therapeutic value ofwhich lies in the facts that by such mechanical action the circu1a-.

tion' of blood is enhanced and stagnation is overcome, capillarystasisis freed and excessive labor is removed from the heart, thelimphatic glands and vessels are also stimulated to better actionthuscausing broken down cells and waste matter to be removed from the bloodplasma, hence the blood ispurified, and in turn the nervous systemreceives blood of a better quality and is brought into a normal andhealthy activity; second, to produce a mechanism that relievesinflammation and promotes the absorption 39 for exercising or massagingpneumatically the tympanum in the treatment of certain diseases andabnormal conditions of the ear.

A further object of the invention is to provide a simple, durable andefficient device for the accomplishment of the above mentioned purposes,as well as other purposes which will become apparent from a perusal ofthe following specification, and an examination of the accompanyingdrawings, in which:

My invention comprises a cabinet 1, in which is placed a motor 2 mountedupon a suitable base 3, the base 3 is in turn slidably held in positionin the guides 4, and adjustably clamped into position by the screws 5.The motor 2 being connected to a shaft 6 with pulleys 7 and 8 mounted onthe shaft 6, and motor 2, respectively. The shaft 6 is journaled inbearings 9 and supports a crank 10 on the outer end thereof, two lugs 11are in turn formed opposite one another on the center line of the crank10, two slides 12 are secured between the lugs 11, spaced equidistantfrom the said center line of the crank 10, and a screw 13 is turnablymounted on the center line of the crank 10, in the lugs 11. A block 14is slidably mounted upon the slides 12, and a-djustably supported by thescrew 13. The center of the outer end of the block 14 is formed with apin 15, and one end of a connecting rod 16 is operatively securedthereon.

A pump 17 is secured in the cabinet 1 with relation to the said crank 10having pump heads 23 secured in both ends of the barrel thereof, and ashaft 18 passes slidably through the longitudinal center of the pumpbarrel within bearings 19, and the pump heads 23 are secured in bothends of the barrel of said pump 17. A piston 20 is slidably secured onthe shaft 18 in the said pump, one end of said shaft 18 being formedbers 24 are eratively' ositionedover said with a-joint 21, and the joint21 is in turn connected to'the connecti rod 16. v

The pumphead 23 is ormed with two valves 22, one being positioned ateach end thereof, as shown in Figure 7. Slide mem valves 22, an areopene and closed by links 25, the links 25 being operated. by the levers26. The levers 26 are adjustably mounted on the fulcrum members 27, andthe lugs 28- are formed on the outer ends thereof with relation tograduated slots 29 in a plate 30,

the plate 30 being secured upon a support in said cabinet 1. The valves31 are also positioned in the two ends of thepump heads 23, as shown inFigure 7 and the flapper 'members32 are hingedly secured to the saidheads 23. The shafts 33 are operatively' mounted in bearings 35,saidbearings being formed on the heads 23, and the cams 34 are in turnformed on the lower ends of said shafts 33, and levers 36 are securedtothe upper ends thereof. Plates 37 with arcuate flanges 40 formed aboutcenter of the shafts 33 are secured to the cabinet'l with relation tosaid levers 36, graduated notches 39 being.

formed in the'outer arcuate flange 46, and

' -lugs 38 are in tu;rn,formed on the said levers 36 to engage withsaidnotches 39. A The ada ter. 41 comprises a bore 42 in which is shdablymounted a sleeve 43, anda head 44 is in turn permanently secured'in thesleeve 43, the screw 45 being arranged to clamp said sleeve. 43stationary within said bore 42 when desired; j

. Theheads 57 aresecured in both ends of the bore 42 and the screws 53and 54 are in heads 57, with the said head' 44. open into sleeve 43. Oilcups are secured in the vaccumulating in the passage 52 may 48 and 49.The sleeve 43 is formed with ports 46 and 47 spaced from one another toalternately open and close the ports 48 and .49 respectively, as thesaid sleeve 43 and-head 44 reciprocate back and forth between thebumpers 58 and 59, with a predetermined stroke, depending upon theposition of the said screws -53-54 and. head 44 within the upper portionof the adapter 41 to su ply oil to the bearing surface between thebox-e42 and sleeve 43 and the overflow oil therefrom be drainedthrough apetcock 56 positioned in the bottom wall thereof.

The pipes '68 and 69 are connected between I the chambers 70 and 71respectively,-in the pump 17, and the passages 51 and 50 respectlvely,1n the adapter 41, connectors 72 and 73 are. formed inthe passage 52 andpipe 69 block,14 on respectively, to detachablyhold a hose 60,theoplposite. end of the hose .60 being secured to a' ousin 62 and cup61, the'housing being rovirfed with flapper valves 63 an 64, an controlarms '65 and 66 respectively. Before operating my invention thepositionof the motor 2 is adjusted tore ate the-distance between thepulleys 7 an 8 to give a tight gripping .or loose sliding beltconnection 74, by sliding the base 3 1n the guides and clamping thescrews 5 in osi- 1n 1.77 will, read .w ere required on the sca e 76. Thestroke of the tions so that the connecting rod 16 is adjustedby'setting' the dead center of the crank 10, to read where required onthe scale 7 5',by turning the screw 13,-thus determining the length ofthe strokes of the iston 20 in the pum openings in t e valves 22 areplacing the slide members 24'thereover, by

the slides 12 a distance from the f 17. The usted by placing the lugs'28 in the required slots 29 thus holding the connecting levers 26andlinks 25 in stationary positions.

The openings in the valves 31 areadju'sted to open and close alternatelyby the flappers 32, said flappers being controlled as required by thecams 34 which are swung about on the center'of the shafts'33 withrelation to the .2

position of the 'levers' 36, the lugs 38 being set into the adjacentgraduated notch 39.

When thetwo valves at each end of the ump 17 are both adjusted tomaintain them' 1n the closed position and'the adapter sleeve 43 is heldstationa by the rods 53 and 54 (Figure '5) being a justed to hold theheads 58 and 59 against opposite sides ofhead 44,

then an ual and too forcible puflr and suction will bodyby theapplicator on 61. The various adjustments ofvalves-an of the length ofthe stroke of the adapter head 44 are provided to soften such action andto regulate e applied to the surface of the.

amount of puif as compared-with suction.

The valves at each end'of ump 17 will, in-

proportion to the extent w 'ic'h they'permit air to enter and to leavethe pum weaken the reciprocatory force applie to v the adapter, butif'these valves are symmetricall adjusted, pufl and suction willbeequal.

he position and stroke of the sleeve in the bore 42 is adjusted whererequired by first clamping the said sleeve 43 to read on the .scale'78,and then adjusting the screw ends 58 and 59 to predetermined distancesfrom the center of said bore 42 to control the open ings between theports 47-49 and 46 -48.

. he operation will be more readily understood if it is borne in'mindthat the electric motor 2 is operatively connected with the pump piston20 in suchamanner as to recip- 'rocate said pistonquite rapidly, and thecross-sectional'area of the piston cylinder 17 1s more than twice thatof the space inclosed by the sleeve 43 of the'adapter, thus providingfor transmission to said sleeve'43 of about double the amount ofmovementfor each reciprocation which is being iven at any time to the piston 20,provi ing the valve closures 24 of the pump cylinder heads 23 areadjusted to the completely closed position. That is to say, while thepump piston moves one inch the sleeve of the adapter will move about twoinches. The extent to which the flapper valves 31 open may also beregulated as desired, but the opening of the valves 31 does notinterfere with movement, by suction, being transmitted from the pistoncylinder 17 to the sleeve 43. There is continuous communication (seeFigures 5, 6 and 7) between chambers 50 and 71 and between chambers 51and 70 hence, since the pump piston 20 reciprocates rapidly and as thearea thereof is more than twice the area inclosed by the sleeve 43,considerable leakage may be permitted thru the valve openings '22without rendering ineffective the action of the sleeve 43 intransmitting the desired variations of atmospheric pressure to theapplicator cup 61.

With the several adjustments made as to the position of the motor 2,crank 10, valves 22, valves 31, head 44 and bumper ends 5859, power istransmitted from the motor 2 through the pulley 8, belt 74, pulley 7,shaft 6 and crank 10 respectively. The turning movement of the crank 10forces the piston 20 in the pump 17 to reciprocate through the shaft 18,and the connecting rod 16 connected thereto.

Pipe 68 leads to cylinder chamber 70 at the right of piston head 20 asviewed in Figures 1, 2-and 6, and pipe 69 leads to the other cylinderchamber 71. Now when piston rod 18 moves to the left (cams 34 holdingclosed flappers 32, both ends of cylinder) the air is sucked fromchamber 51, Figure 5,

and the suction draws sleeve 43 toward the left end of chamber 42, untilpartition 44 strikes the bumper 59. At the same time this suction actionis taking place in the right end of the cylinder 17 and left end of theadapter there is also a compression action in the left end of saidcylinder and right end of the adapter as follows: Piston head 20 movingto the left creates a pressure in chamber 71 of pump cylinder 17. Thispressure is conducted through pipe 69 to chamber 50, from where itforces sleeve 43 toward the left. Hence on one side of partition 44there is suction isochronously with a compression on the other side,thus operating the sleeve.

The housing 62 is provided to afford a means whereby, without changingthe action of the machine, a continuous suction, a continuous blowing oran alternating suction and blowing effect may be obtained merely byoperating the valves. 63--64 by the. controls 6566 respectively with thecup 61 on the body. The mode of pneumatic delivery machine in general.The valves can also be permanently set in the adapter 41 forany mode ofpneumatic delivery when using various sized cups 61.

The stroke of the crank 10 is lengthened or shortened when changing froma small cup 61 to a larger cup 61, to provide the necessary pneumaticvolume.
